Metric characterizations of upper semicontinuity

open access: yesJournal of Mathematical Analysis and Applications, 1979
AbstractWe characterize upper semicontinuity of multifunctions in terms of upper Hausdorff semicontinuity, measure of non compactness and active boundary. The results are applicable in optimization, theory of best approximation and in metrizability theory.

The lower semicontinuity of the Frobenius splitting numbers [PDF]

open access: yes, 2010
We show that, under mild conditions, the (normalized) Frobenius splitting numbers of a local ring of prime characteristic are lower semicontinuous.Comment: 13 pages, revised version, to appear in Mathematical Proceedings of the Cambridge Philosophical ...

Attractors of multivalued semiflows generated by differential inclusions and their approximations

open access: yesAbstract and Applied Analysis, 2000
We prove the existence of global compact attractors for differential inclusions and obtain some results concerning the continuity and upper semicontinuity of the attractors for approximating and perturbed inclusions.

Asymptotic behavior for non-autonomous stochastic plate equation on unbounded domains

open access: yesOpen Mathematics, 2019
We study the asymptotic behavior of solutions to the non-autonomous stochastic plate equation driven by additive noise defined on unbounded domains.

Upper semicontinuity of pullback attractors for a nonautonomous damped wave equation

open access: yesBoundary Value Problems, 2021
In this paper, we study the local uniformly upper semicontinuity of pullback attractors for a strongly damped wave equation. In particular, under some proper assumptions, we prove that the pullback attractor { A ε ( t ) } t ∈ R $\{A_{\varepsilon }(t)\}_ ...

Separating sets by upper semicontinuous and Darboux upper semicontinuous functions

open access: yesTopology and its Applications, 2013
Abstract In this paper we characterize the pairs ( A 0 , A 1 ) and ( A − , A + ) of disjoint sets which can be separated by an upper semicontinuous function and by a Darboux upper semicontinuous function.

Long-time dynamical behavior for a piezoelectric system with magnetic effect and nonlinear dampings

open access: yesElectronic Research Archive, 2022
This paper is concerned with the long-time dynamical behavior of a piezoelectric system with magnetic effect, which has nonlinear damping terms and external forces with a parameter.

The Wu metric is not upper semicontinuous [PDF]

open access: yesProceedings of the American Mathematical Society, 2007
We give an example of a bounded pseudoconvex domain in C", the Wu metric of which (associated to the Kobayashi-Royden or the Azukawa metric) is not upper semicontinuous.

Debt Ceilings With Fiscal Intransparency and Imperfect Electoral Accountability

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We study optimal debt ceilings in a political‐agency model with uncertainty about both policymaker type (benevolent or selfish) and economic state (good or bad). Elections generate disciplining and selection effects that differ across pooling, hybrid, and separating equilibria induced by different ceilings.
